anybody else ever stay out too long and think you're back may never be straight again??

Eagleye my dad made one for me about 1965 they are very simple. Take an extension cord and cut the female end off (2 strand no ground) separate the two and fold the black one back and tape it to the cord solder the other strand to a piece of smooth rod you have sharpened on the other end. Fashion a wooden handle that covers the solder joint. Water a location until damp and stick it in the ground. Then go plug it in go back where you put the probe and feel the ground about a foot back from the probe. You will either feel the electricity or not. If not go back to the outlet and rotate the plug 1/2 turn you should then be able to feel the electricity at the probe site.
A couple of words of caution;! The ground needs only to be damp! Standing water will conduct all of the current and give you a nasty shock!
Always have the cord unplugged when handling the probe to avoid a bad shock. Stick the probe into the ground and THEN PLUG IT IN. I failed to follow those instructions an got quite a jolt. Use at your own risk they do work but they can also electrocute you if you get careless.

Saw many strange things o a golf course late at night.
Naked women dancing on the green--I did have my light off,so they never knew I was there.
Picking on a fairway one night,I saw lights coming from behind the fairways hill.Over the hill came a car and straight down the fairway at me.
Caught 2 guys one night trying to break into one of the storage buildings on the course.--One of the reasons I was allowed on the course,they liked the extra eyes out there and they appreciated the way I handled myself.

One thing to remember on a golf course---when the hair on the back of your head stands up----it's time to run like all get out.Lightening is a big killer.
